The trace anomaly for a chiral fermion
Chang-Yong Liu
In this paper, we study the problem of trace anomaly for a chiral fermion. To find whether there exists a parity-odd term (Pontryagin term), we use a modified Breitenlohner-Maison-…

Investigation of Pontryagin trace anomaly using Pauli-Villars regularization
Chang-Yong Liu
In this paper, we investigate the Pontryagin trace anomaly for chiral fermions in a general curved background using Pauli-Villars regularization. We use both Feynman diagram method…
